What is Pollarding: A Guide to this Pruning Technique
As homeowners and garden enthusiasts, one of the most important things we can do to maintain the health and beauty of our trees is to prune them regularly. There are many different pruning techniques, but one that has been around for centuries and is still widely used today is pollarding. In this article, we will explore what pollarding is, how it works, and when it is appropriate to use it on your trees.
What is Pollarding?
Pollarding is a pruning technique that involves cutting back a tree's branches to its main trunk, or to a framework of branches that was established during previous pollardings. Essentially, it is a form of severe pruning that keeps trees at a specific height and encourages new growth from the cut points.
This technique originated in Europe in the Middle Ages, where it was used to produce wood for firewood, fencing, and even basket weaving. Today, it is more commonly used as an ornamental technique to keep trees smaller and more manageable in urban areas.
How Does Pollarding Work?
When a tree is pollarded, all of its major branches are cut back to the same point, typically several feet above the ground. This creates a "pollard head," which is a knobby mass of branches and twigs that will eventually develop into a new crown of foliage.
Over time, the new growth from the pollard head will extend upwards and outwards, creating a dense canopy of leaves and branches. The process of pollarding needs to be repeated every few years to maintain the desired height and shape of the tree.
When is Pollarding Appropriate?
Pollarding is not appropriate for all trees or situations. It is generally best suited for deciduous trees, such as poplars, limes, and willows, that have a tendency to grow quickly and become too large for their surroundings. It is also ideal for trees that are growing in confined spaces, such as along city streets or in small gardens.
However, it is important to note that pollarding should only be done on healthy, mature trees that are well-established. Young trees, or those that are stressed or damaged, may not have the energy reserves to recover from such a severe pruning.
The Benefits and Drawbacks of Pollarding
One of the biggest benefits of pollarding is that it can help control the size of trees, which is especially important in urban areas where space is limited. It can also promote new growth and increased density, which can be beneficial for wildlife habitat.
However, there are also some drawbacks to pollarding. One of the main concerns is that it can weaken the overall structure of the tree, making it more susceptible to wind or storm damage. It can also be aesthetically unappealing, as the knobby pollard heads can look unnatural and unsightly to some people.
In conclusion, pollarding is a pruning technique that has been used for centuries and continues to be a popular option for maintaining the health and beauty of trees in urban areas. While it is not appropriate for all trees or situations, it can be a useful tool for controlling size, promoting new growth, and enhancing wildlife habitat. If you are considering pollarding your trees, be sure to consult with a professional arborist to ensure that it is done correctly and safely.
